COMPANY, OF NEW YORK,

WATER-GAGE.

Application filed May 31, 1913.

To all whom it may concern:

Be it known that I, ALBERT W. MORSE, a

. citizen of the United States, residing at New York, in the county ofNew York and State of New York, have invented certain new and usefulImprovements in \Vater-Gages, of which the following is a specification.

This invention relates to water gages, and its novelty consists in theconstruction and adaptation of the parts as will be more fullyhereinafter pointed out.

Gages of this character, especially where they are to be used onlocomotives and adapted to measure the height of bodies of very hotwater, are apt to have their sight glasses shattered under the influenceof the unequal temperatureson their opposite surfaces and are especiallyapt to leak because of the unequal expansion and contraction of thecontacting parts. They should, therefore, be most carefully packed, andthe purpose of this invention is to provide a device of this character,simple in form, readily packed and easily maintained in an efficientcondition.

In the drawings, Figure 1 is a transverse horizontal section of a deviceembodying the invention, and Fig. 2 is a miniature front elevationthereof; Fig. 3 is a transverse section of a different form of thedevice, and Fig. 4 is a miniature front elevation thereof. Fig. 5 is atransverse section of a yet difierent form of the device, and Fig. 6 isa miniature front elevation thereof.

The device comprises first of all a'casing having two side walls 20, oneon each lateral edge of a centrally placed sight glass 30 which isprovided with the usual rear flutings or recesses indicated at 31. Eachwall 20 of the .casing has at its front end an inwardly turned flange 21and between the two flanges is a longitudinal sight opening indicated at32. The sight glass is smaller in breadth than the space between thewalls of the casing, and it does not extend to the rear wall of thelatter so that there is left back of this glass a space33 adapted toreceive the column of water, the height of nut 41 adapted to fit overthe set screw 40 PatentedJuly 31, 1917. Serial No. 770,884. 3 I

(Figs. 1 and 3). This nut bears against packing 11 and compresses ittightly against the set screw 40. I

Between the front side of the glass 30 and each flange 21 there isarranged a suitable packing 50 and back of this and on each edge of theglass is arranged another packing 51, and back of each piece of thelatter packing there is arranged a plate 52' and interposed betweenthese plates and the set screw 40 is a compression member 42. f

It will be understood, of course, that the casing at its top and bottomis provided with fittings by means of which it is connected to thereservoir or receptacle containing the water to be measured, and thatthere are provided drainage cocks and the usual adjuncts common to theart.

In Figs. 3 and 4 there is illustrated a form of the device in which thesight glass is substantially square in section and in which thesidewalls of the casing are arranged parallel to each other instead of beingat an acute angle. The compression member 42 is also substantially inthe form of a fiat bar, and the plates 52 instead of be-. ing straight,are L-shaped. The principle of the invention, therefore, is the same asbefore.

In Figs. 5 and 6 there is illustrated a further modified form in whichthere is shown a sight glass comprising a plurality of elements betweenwhich there are arranged flanges 210 which overlap the element on 7 eachside. The packings 51 in this modification are not only placed betweenthe two outer sight glass elements and the walls 20, but are also placedbetween such elements and the central sight glass element. The lock nut41 is also placed outside of'the extension 43 instead of inside. Thereis, however, no departure from the principle of the invention in thismodification, and it simply serves to illustrate the application of theinvention to varying circumstances. In this form, it will be noted thatthe inner end of the set screw 40 is tapered and operates between theplates to force them apart.

It will be noticed that in the forms ofth'e device illustrated in-Figs.1 and 5 that-the sight glasses are in the form of a truncated sector(disregarding the flutings 31). This form serves an important purpose insecuring the result that the glass on account of its front curvedsurface uniformly increases l in thickness from each edge toward themiddle and consequently it is thickest at the middle where it is notsupported or reinforced as it is at the edges.
